I 'Thepresent' invention relates to signals,

' which while primarily intended for-use as an automobile signal is capable of many without departing from the invention. It

other analogous uses, and that its general application is contemplated by the claims.

' The invention embodies a novel construction' and arrangement of parts, including a signal arm capable of being folded and arranged within a housing, entirely concealed from view, and which can be quickly and serles being indicated generally at A in Figeasi-ly "projected therefrom for use when desired. 1

In carrying out the invention I contemplate'asignal arm construction, capable of beingfolded-or extended for use as the occasion may require, with said arm having an extended movement approximately three times as far as that of the operatingelement 1 therefor, and requiring but'little effort to actuatefsa id arni'to either its extended or folded position.

-The nature and advantages of the invention'will be better understood when thev 7 ably of triangular outline, and is characterized by an extension 15, folded from one following'detail description is" read in con- 7 nection with the accompanying drawings, the invention residing in the construction, combination and arrangement of parts as claimed. a f

' plates forming part ofthe arm.

Figure 7 is a View showing the arm extended with the housing in section. I w The signal embodies-a housing indicated generallyat 10, one side of which isopen to receive the signal arm when the latter. is

folded as clearly illustrated in Figure 4.

This housing 10 may be constructed from any suitable material and also vary in size may also be mounted onany suitable support,;being herein illustrated on a suitable Th e signal arm comprises spaced parallel series of pivotally connected sections, one

ure 2 andthe other series at B. The sec- ,tionsof each series are constructedas illustrated in Figures 5 and 6, wherein one section isindicated at'lS and the other section at 14. These sections are alternately arranged in each series, w th the correspondi'ng sections of the respective series arranged directly opposite each other. "In Figure -5 the section 13 is" perfectly fiatand pr0 'vided with countersunk holes or openings,

and preferably of thecontour, illustrated,

while the section 14 in Figure 6 is preferextension iss'pacedfrom its section, and is also separated therefromfor a portion of itslength adjacent theedge from which it' is formed. l 1 7 As abovestated these sections are alternately disposed throughout the length of at 14' in Figure 6, these corresponding sections of the respective series being pivotally I mounted upon the opposed side walls of the housing 10 by suitable links.

at 19 is arranged vertically and hasone end 130f each series has one end pivoted as at -22 to the adjacent =1ink and its. other end O F CE l ,ad acent'corners.

- Into yinspection of Figure '7 that while the sections" 13"and 14 are alternately disposed throughout the length of each series, every other section 14 is reversely disposed, that o [is to say that this extension 15, is arranged j above orbelow the extension of the next corresponding section, and that'the'extennected with the next' corresponding [section In addition to the-sections: above described, the signalv arm also includes two substantially U-shaped outer sections 24iand 25 respectively, which are arranged one -within the other and pivotally connected as, 1'

[at 26. These sections are also arranged between the series A and B and are pivotally connected as at 27 with the adjacent sections of the ,respective series. These two 'outer-v most sectionsQe and 25 are designed to give,-

' gthearman arrow-like formation when the arm ,isvextended for use as-lllustrated in ',Figure 1, It will be noted upon inspection ofFigure 6 that thesection 14: is provided- ,with astop 1ug.28 to prevent these sections from going past center lwhen the arm is folded ,within the housing, while the outer- .mostgs'ectionsQi and 25 are constructed to, engageeach'other when the arm is folded to preveritthese sections from moving past reenter, Howeverthe other sections 13 are not providedwith any stop lugasthese sectionsfgmove past center when the arm is ,j folded, and this action assists in moving the 'outermost'sections 24 and 25 further within the housing when the arm is folded. If

n desired-corresponding sections, of the irespective series may be connected together by a Ushaped bracket 29 to give the signal armthe desired strength and rigidity." f While the arm may be projected to its extended position for use, or foldedwithin g-gtheihousing "in its'neutra'l position, by any 1&5

suitable means, I preferably employ an op- ,eratingrod 30 which is mounted for sliding movement through the rear wall ofthe housing 10 and its support.-v The forward endofthis rod is connected with a suitable j bracketBl (arranged between the series A jand B of'said sectionsandconnected with :corresponding sections of the respective :series, ,while theouter endofv the arm is preferablyprovided witha knob or handle =32. WVith this: construction the rod 30fis essaryto move the rod 30 a slight distance ,to quickly project the arm to its active position fOruse, or to retract the arm to its folded position withinthe housing. The construction is such, that the signalling arm will be movedapproximately three times the distance of that required of the rod 370 jtoactuate the arm in either directionf sion 15 'ofea'ch section 14 is pivotally con- I When the signalling arm is extended for use, it presents a complete face or surface which can carry lettering'or other indicia. ,,S 8GiZlOI1 13 ofeach series is-pivoted onto: the adjacent sectionl i betweenthe latter and, its extension 15,,while allof the sections .13 are also pivotally connected together at their While; it is believed that from the ,foregoing description the nature and advantages of the invention will bereadily apparent,
